"Not in the least. You see, he recognised his private mark at once, and Brighton is not so prosperous a place that a man could sell a £70 cigar-case and forget all about it—that is, a second case, I mean. It's most extraordinary."
"Rather! Make a magnificent story, Marley."
"Very," Marley responded, drily. "It would take all your well-known ingenuity to get your hero out of this trouble."
Steel nodded gravely. This personal twist brought him to the earth again. He could clearly see the trap into which he had placed himself. There before him lay the cigar-case which he had positively identified as his own; inside, his initials bore testimony to the fact. And yet the same case had been identified beyond question as one sold by a highly respectable local tradesman to the mysterious individual now lying in the Sussex County Hospital.
"May I smoke a cigarette?" David asked.
"You may smoke a score if they will be of any assistance to you, sir," Marley replied. "I don't want to ask you any questions and I don't want you—well, to commit yourself. But really, sir, you must admit—"
The inspector paused significantly. David nodded again.
"Pray proceed," he said: "speak from the brief you have before you."
"Well, you see it's this way," Marley said, not without hesitation. "You call us up to your house, saying that a murder has been committed there; we find a stranger almost at his last gasp in your conservatory with every signs of a struggle having taken place. You tell us that the injured man is a stranger to you; you go on to say that he must have found his way into your house during a nocturnal ramble of yours. Well, that sounds like common sense on the face of it. The criminal has studied your habits and has taken advantage of them. Then I ask if you are in the habit of taking these midnight strolls, and with some signs of hesitation you say that you have never done such a thing before. Charles Dickens was very fond of that kind of thing, and I naturally imagined that you had the same fancy. But you had never done it before. And, the only time, a man is nearly murdered in your house."
"Perfectly correct," David murmured. "Gaboriau could not have put it better. You might have been a pupil of my remarkable acquaintance Hatherly Bell."
